Legal claims defining the scope of protection, as filed with the USPTO.
1. Method for dynamic control of the performance of an aircraft computed on the basis of a real aircraft data input file and a computation data input file, using a computerised flight manual running on a terminal equipped with a commercial operating system, which comprises the following steps: a step of computing the performance of the aircraft on the basis of said real aircraft data input file, and said computation data input file, and obtaining at least one first result file, a step of computing reference performances on the basis of a reference data input file, and obtaining at least one third result file, which step is performed in parallel with the previous step, a first step of comparing the at least one third result file with the at least one reference result file, so as to detect any malfunction of the operating system with the application of numerical margins tolerated on the results of the result files, a step of deleting the at least one first result file and sending an error message to the user if the result of this first comparison step is negative.
2. Method according to claim 1 , which comprises: a second step of computing the performance of the aircraft on the basis of the real aircraft data input file and the computation data input file, and obtaining at least one second result file, a second step of comparing the at least one first result file and the at least one second result file, a step of deleting the first and second result files and sending an error message to the user if the result of this second comparison step is negative.
3. Method according to claim 1 , which comprises: a preliminary step of verifying data integrity control algorithms established on modules for computing the flight manual, and on configuration files used by it.
4. Method according to claim 1 , which comprises: a step of verifying, after reading the input files, data integrity control algorithms established on these input files, prior to each computation step.
5. Method according to claim 4 , which comprises: a step of verifying, after writing the result files, data integrity control algorithms established on these input files, after each computation step.
6. Method according to claim 2 , which comprises: a step of checking the comparison module performing the second comparison step, before it performs said second comparison step.
7. Method according to claim 3 , wherein each data integrity control algorithm is a 32-bit-type checksum.
8. Method according to claim 1 , wherein the operating system is the Windows system.
9. Method according to claim 1 , wherein the aircraft is an airplane.
10. Aircraft using a computerised flight manual operating on a terminal equipped with a commercial operating system, which comprises: a first module for computing aircraft performance on the basis of a real aircraft data input file, and a computation data input file, and obtaining at least one first result file, a third module for computing reference performances on the basis of a reference data input file, and obtaining at least one third result file, a first module for comparing the at least one third result file with the at least one reference result file, so as to detect any malfunction of the operating system with the application of numerical margins tolerated on the results of the result files, a module for deleting the first result files and sending an error message to the user if the result of this comparison is negative.
11. Aircraft according to claim 10 , which comprises: a second module for computing aircraft performance on the basis of the real aircraft data input file and the computation data input file and obtaining at least one second result file, a second module for comparing the at least one first result file and the at least one second result file, a module for deleting the first and second result files and sending an error message to the user if the result of this comparison is negative.
12. Aircraft according to claim 10 , which comprises: a module for verifying data integrity control algorithms established on modules for computing the flight manual, and on configuration files used by it.
13. Aircraft according to claim 10 , which comprises: a module for verifying, after reading the input files, data integrity control algorithms established on these input files, prior to each computation step.
14. Aircraft according to claim 13 , which comprises: a module for verifying, after writing the result files, data integrity control algorithms established on these input files, after each computation step.
15. Aircraft according to claim 11 , which comprises: a module for checking the comparison module performing the second comparison step, before it performs said second comparison step.
16. Aircraft according to claim 12 , wherein each data integrity control algorithm is a 32-bit checksum.
17. Aircraft according to claim 10 , wherein the operating system is the Windows system.
18. Aircraft according to claim 10 , wherein the aircraft is an airplane.
